Sound Effect Playing Infinitely

It appears there is a sound effect that gets played on a timer that isn't being cleared when a battle ends/character dies.

Go into the Shield Training and play the last node on the right for day 1. The one with the AIM Mecha in it. There is a timed beep sound that plays every 5-10 seconds (I think I remember it playing when his CD moved in the old app). Play a turn or so until you hear it play once. Then win/lose/exit the battle. Now listen carefully and it will continue to play over the background music every 5-10 seconds or so. It does this forever until you close the app. Then it's gone. The timer to play it must not be clearing properly.
